In a portion of a gene, the nitrogenous base sequence is T-C-G-A-A-T. What mRNA would this sequence make?
|
|
A-C-G-T-A-A
|
|
|
A-G-C-U-U-A
|
|
|
A-G-C-T-T-A
|
|
|
U-G-C-A-A-U
|
Explanation:
Detailed explanation-1: -In a mRNA sequence of Nitrogen base is 5’ AUG GUG CUC AAA 3’.
Detailed explanation-2: -DNA utilizes four bases, adenine (A), guanine (G), cytosine (C), and thymine (T), in its code. RNA also uses four bases. However, instead of using ‘T’ as DNA does, it uses uracil (U). Therefore, if your DNA sequence is 3’ T C G T T C A G T 5’, the mRNA sequence would be 5’ A G C A A G U C A 3’.
Detailed explanation-3: -The given sequence on DNA strand is as follows: ATCTG. thus, the complementary one on RNA will be: UAGAC.
Detailed explanation-4: -The codon on mRNA are CAU-CCU-AAA-CUG.
